You shuffle them in the deck and break the core paladin mechanics. BTW Emerald portals are sown with paladin frame in the “My collection”
What mechanic are you talking about ?
I just tested and the portals don’t count as neutral cards
They even count as class cards for service bell

Are you sure it’s not another cards that got shuffled in your deck ? like an amalgam summoned by a 1-cost portal
